Because a very low abundance of MSCs is present in bone marrow (approximately one Per 10〓-10〓 nucleated celled), ex vivo expansion produces a significant increase in the number of MSCs that can be very important.

然而，人体内骨髓中MSC的含量极其稀少，每1×〓-1×〓个单个核细胞中大约有1个MSC，组织工程中对种子细胞的数量要求巨大，如此微量的MSC难以满足组织工程的需要，因此体外纯化和扩增MSC就显得尤为重要。
